Title: A multi wavelength locking method and apparatus by using acousto-optic tunable filter
Inventor: KIM BONG GYU
IPC: H04B10/572
Filed: 2001-12-18
Abstract: PURPOSE: A multiwavelength fixing method and apparatus using an acousto-optic tunable filter is provided to reduce a signal noise due to a pilot signal by applying the pilot signal to an acousto-optic wavelength filter with different transmission wavelength and frequency conversion according to frequency of an acoustic wave. CONSTITUTION: Lights with different optical frequencies outputted from a light source are multiplexed by a multiplexer(12) and applied to a WDM(Wavelength Division Multiplexing)(10). The multiplexed optical signals are partially transmitted to a transmission system and partially to an acousto-optic tunable filter(14) for multiwavelength fixing. An etalon filter(16) has different transmission characteristics according to a wavelength, so that even if a light with a strength is inputted, the light is outputted with a different strength according to wavelength. An optical divider(15) divides a light into two to use one to measure a light strength and input the other to the etalon filter(16), thereby measuring strength and wavelength of inputted light. Two optical detectors(18,19) detect electrical signals and inputs them to a band pass filter(22). The band pass filter(22) passes only a required specific frequency of plural frequencies included in the inputted light and removes the other remaining frequencies than the specific frequency. A wavelength controller(21) detect wavelength information on corresponding optical frequency by optical frequencies of each light source(11) by using the electric signals with the wavelength detected by the optical detectors(18,19), and compares the detected wavelength information and a desired wavelength of the light source(11). If there is a difference between the two wavelengths, the wavelength controller(21) changes an environmental condition of the light source(11) to obtain the desired wavelength.
